These things are great but it also depends on how much space you have to utilize. I was givena huge bottle warmer in my shower and it took up a lot of space. I had minimal space to begin with. Just so you know, you can also just take a cup half filled with hot water and dip the formula bottle in it for a little and bottle will heat up just fine enough for baby. Also I think you can always boil the bottle in a pot full of water to sterilize.
